In order to realize robust fault location and isolation of distribution systems under the condition of incomplete information, this paper proposes using the relevance among each phase of fault information, three-phase fault currents and both reported by each feeder switch after fault to amend the omitted and false fault information reported by terminal equipment. And then, a method is proposed to achieve rapid fault location of distribution system’s fault section by analyzing the topology, dividing the system into independent minimum distribution area and combining the corrected fault information reported by the above minimum distribution area. The simulation results show that the algorithm can effectively correct the missing and false fault information in order to achieve rapid fault-tolerant location of distribution system’s fault section.
